Spiralized Summer Squash Casserole with Gluten-Free Breadcrumbs

Happy August!

There are two types of recipes that I get requests for the most. First, it’s “easy, quick weeknight recipes” and second, it’s “dishes I can bring to a potluck.”

This recipe satisfies the second request! If you’re looking to bring a side dish to a BBQ or potluck or even just want to make something easy to share, this casserole is it!

It’s almost like a gratin, and the little chip slices are made with the Inspiralizer. You can see how to do that exactly, here.

I used yellow squash and zucchini to make this gratin, to truly use up all of that summer squash! The squash cooks and softens, releasing a bit of moisture into the casserole dish, making a warm sauce once it melts with the Parmesan cheese.

The gluten-free breadcrumbs are really the star of the show here. If you haven’t made them yet, let this be your inspiration. I even have a video on how to make them! They save well in the fridge, too – so you can totally make a big batch and use them all week.

Now, onto other matters. It’s officially August!

Starting today, I’ll be posting only three times a week, instead of four times a week. I’m decreasing the posts and preparing the next few months for my leave. I’ll be posting Sunday, Monday, and Wednesdays!

You can also find new posts on inspiralizedali (I post twice a week there), if you’re looking for some more lifestyle content.

Thanks for your understanding, as always!

Spiralized Summer Squash Casserole with Gluten-Free Breadcrumbs

Prep Time15 mins
Cook Time30 mins
Total Time45 mins


  • 2 medium zucchini
  • 2 medium yellow squash
  • 3 tablespoons extra virgin olive oil
  • salt and pepper
  • 2 tablespoons grated Parmesan cheese
  • For the breadcrumbs:
  • 2 tablespoons almond meal
  • 1/8 teaspoon dried oregano flakes
  • 1/8 teaspoon dried basil flakes
  • 1/8 teaspoon dried parsley flakes
  • 1/8 teaspoon garlic powder
  • salt and pepper to taste
  • 1 teaspoon water


  • Preheat the oven to 350 degrees.
  • Place a medium skillet over medium heat and coat with cooking spray. Meanwhile, in a small bowl, combine all of the ingredients but the water for the breadcrumbs and mix together. Add in the water and use your hands to form a dough – it should end up in a ball. Crumble the dough ball into the heated skillet and continually break up with a wooden spoon. Cook for 2-3 minutes or until breadcrumbs break up, harden and become “toasted.” Set aside in a bowl.
  • Slice the zucchinis and yellow squashes halfway through lengthwise, careful not to pierce through the center. Spiralize on Blade A to yield chip-slices.
  • Grease a baking dish with cooking spray. Lay the zucchini in an even layer. Top with yellow squash. Top with zucchini. Top with yellow squash. Then, top with zucchini. Keep going until all your squash is used. Sprinkle over with the prepared breadcrumbs. Drizzle over with olive oil and season with salt and pepper.
  • Cover the dish with foil and bake in the oven for 30 minutes. Remove the foil and immediately sprinkle with Parmesan cheese. Serve.

Hi! Looks Devine! Is the recipe supposed to have Parmesan cheese in it? You say the squash melts with the Parmesan to make a sauce, but I don't see it listed anywhere else in the recipe. Thanks!!!

I made this for dinner tonight with a pound of Italian sausage and a tablespoon of fennel seeds. It was excellent! My whole family loved it. Will make again. Great way to enjoy all that beautiful zucchini in our garden with a nice Italian flair! Thanks for the recipe!

cauliflower and carrot masala, totally normal meal on thanksgiving eve, right? 😅🥄

tomorrow we’re going to my BIL’s to hang out with Lu’s side of the family, and I’m excited to see everyone (it’s been YEARS!) and have the kids spend time with their cousins, aunts and uncles 🙏🏼

for the curry, simmer cauliflower, carrots, a jar of @mayakaimalfoods, and 2 cups of @bonafideprovisions veggie broth in a large pot for 20 minutes or until thickened to your preference. add cooked lentils, stir, and serve with jasmine rice, chutney and toasted naan. easy 30 minute meal 👏🏼 not exactly thanksgiving-friendly, but worth a share!

safe travels today and tomorrow and wishing everyone a safe and happy thanksgiving 🦃 I’m so grateful for you

rio and sol are 10 weeks old today! 👶🏻👶🏻 10 weeks! 2.5 months! let's chat.⁣ 🙏🏼

rio is much like luca. he loves to be held and needs more touch or movement to fall back asleep. he loves to stare at things in a serious way, especially high-contrast art for babies, so I love reading him books while I hold him (he's the best snuggler.)⁣

sol is my chill boy. he's a good sleeper. he smiles and loves to talk. he's squealing and making his goo-goo-ga-ga sounds all the time, I love chatting with him. he's a bit more like roma as a baby, a bit more independent. he makes the funniest faces and serves up the grimaces like luca used to.⁣

what's funny about twins is that just when you think you know their personality differences, they change - they'll swap. 🤷🏻‍♀️ and to tell them physically apart, there are two key differences:⁣
⏺ rio has a wider head and sol has a more narrow, round forehead⁣
⏺ rio weighs a full pound more than sol⁣

and yes, I have mixed them up a few times! I've been carrying one around, talking to them by name, and then all of a sudden, when I go to pick the other one up, I realize I mixed them up! 😱when they're not together or you're not looking at them straight on, it can be confusing! one of my favorite games is texting my family photos of them and saying, "who's who?!" they get it right 50% of the time, ha!⁣

so far, having twins is just so cool. it's so cool that there are two of them and they are identical! every week that goes by, their personalities shine and I am having so much fun getting to know them - and getting twice the cuddles. and yes, they do sometimes cry at the same exact time, but you just have to pause, gather yourself, and get your soothing game on.⁣ 💪🏼

I have to say, while having newborn twins and 2 other older kids at the same time has its challenges, I give a LOT of credit to those who have twins as their first baby experience - I can't imagine going into this not knowing what I already knew about raising babies. talk about overwhelming! 🤯 all moms are crushing it, but especially those first time moms with multiples - woop! bless you. 👏🏼 #identicaltwinboys #identicaltwins #monoditwins #twinmom #twinboys
